“I have now completed two separate contracts with Roman, and he consistently exceeded my expectations and those of upper management, whom I included in meetings with Roman on several occasions. I have managed several dozens of consultants over the course of the past 15 years and I can honestly say that Roman ranks at the very top of my list. To complement his terrific technical (both architectural and development) skills, his command of the English language is better than most Americans, as he has used the English language for his entire life in addition to his native language. He is both a team player and an independent thinker. I look forward to hopefully working with him on future projects. Just super.”
